580 Dr. R. von Willemoes-Suhm on Observations 



tions of the Pacific. I do not think it advisable to fill up this report 

 with general remarks on a fauna which is so well known as the surface 

 of the Atlantic. 



The Islands of the Atlantic. 



On our first visit to the Madeira fish-market we got a number of Mora 

 mediterranea specimens, a fish which we had got a few days before in 

 deep water. We also secured a fine Beryoc, which, being one of the oldest 

 genera of Acanthopterygians, is especially remarkable. 



In St. Thomas we spent a few days after a four weeks' cruise, but did 

 little in the way of collecting, except catching some fish in the trammel 

 and some dredging. The Professor secured in this place a great number 

 of Echinoderms. 



Numerous excursions were made in Bermudas, partly inland, when I 

 tried to catch as many insects as possible on the beach, where the 

 shallow-water animals were secured by wading. Hungary Bay was my 

 chief place of resort. Here the forest approaches the beach, and afforded 

 opportunities for collecting of all kinds. There mangrove-trees were 

 growing in large swamps, crowded with a Grapsus which ascended these 

 trees ; and under the stones which covered the muddy ground I found 

 plenty of land-crabs belonging to different genera of the Telphusidse. 

 When looking for these I discovered a land-Nemertean, being the first 

 one found in the western hemisphere (the only animal of this kind having 

 been found by Semper in the Philippines). This species was described 

 and figured in the 'Annals and Magazine of Natural History' for 

 1874 (xiii. p. 409), under the name Tetrastemma agrieola. 



In Bermudas we also made frequent excursions in the steam-launch, 

 which enabled me to get specimens of a Nebalia which I had noticed 

 before among Crustacea collected by Mr. Murray. This species (N. Ion- 

 gipes), which I have worked out and described in the ' Transactions of 

 the Linnean Society,' is remarkable in many ways, as its legs are far less 

 " phyllopodal " than in the other species known before, and, as in the 

 male of this American Nebalia, it is the first and not the second antenna 

 (N. Geoff royi) which has been enlarged and transformed into a prehensile 

 organ. 



In the Azores we had only a few days, and in Madeira there was no 

 landing on account of the small-pox being there. Our next collecting- 

 places were the Cape-Verd Islands, first St. Vincent and then St. Iago. 



In the barren island of St. Vincent I made a trip into the mountains, 

 and was very much struck by the utter barrenness of the place. Cathartes 

 percnopterus, crows, and a few small birds were the only living beings 

 we saw flying about. Under stones we got some geckos (Platydactylus) 

 and a Lycosa, and near a water-pool a few dragonflies were seen. These 

 were, with the exception of a few beetles, the only animals which could 

 be found, though we looked about a good deal.
